[Zope] How to I use aquisition in an external method?

[Chris McDonough]

Dylan,

I usually pass "this()" in to an external method to get a handle on
acquisition from an external method.

e.g.:

<dtml-call "emMyExternalMethod(this())">

def myExternalMethod(context):
    if context.folder.attribute:
        do something
    else:
        do something else

this() generally refers to the folder containing the dtml method.  in
the external method, you can use acquisition through this object.

HTH,

Chris
